Acetylated starch(TVA Starch) is created by a process of natural starch reacting with acetic anhydride or vinyl acetate. Ester groups have effect on the prevention of amylose retrogradation in starch. This modification prevents gelling and weeping and maintains structural appearance of the processed product. This also improves its stability after the freeze-thaw process, improves the water-holding ability and lowers gelatinization temperature of the starch, increasing peak viscidity and improves the gel clarify. The result of this modification is a stable starch used to produce durable pastes through several freeze-thaw cycles and to prevent water leakage.
